LOUIS M. BEEBE, orKANsAs CITY, iviissounr.

CASTER.

Application filed March 22, 1922, Serial N0. 545,720.

T 0 all whom it may concern Be it known that I, LOUIS M. BEEBE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Casters, of which the following is a specification;

In a great many articles of furniture having four legs it is common for only three legs to rest'on the floor, due to slight differences in length of the legs, or unevenness of the floor, giving rise to annoyance from rocking of the furniture when touched, especially if the same be in the form of a table.

By applying my device to furniture ance above referred to can be readily overcome by adjusting the casters vertically until all four rest firmly upon the floor.

In order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which: I

Fig; 1 is a side elevation of a caster for furniture legs equipped with the invention.

Fig. 2 is an irregular vertical section on line II-II of Fig. 1.

Fig. 3 is an inverted detail perspective view of an adjustable member constituting part of the invention.

Fig. 4 is an inverted detail perspective view of a tubular member constituting a part of the invention.

Fig. 5 is a detail perspective of a split washer.

Referring now in detail to the different parts disclosed by the drawing, A designates the lower portion of the leg of a table or other article of furniture. B designates a caster of standard make mounted in a frame consisting of a yoke C, a ball-bearing D, and a shank E extending through the ball: bearing D and fixed to the yoke C.

2 designates a tubular member constituting an important feature of the invention. Said tubular member has a reduced upper portion 4:, an internally threaded lower portion 6 and a marginal flange 8 at its lower end provided with upturned points 10 adapted to be driven into the lower end of the upper end by the reduced portion of the 2 1 designates a spring washer adapted to rest on the upper end of the member 12 and frictionally grip the shank E to prevent the same from coming out of the tubular member 2 when the leg A is raised.

lVhen the parts are assembled as shown I in Figs. 1 and 2, it is evident that if the ball-bearing D is below its seat 16 when the caster B rests upon the floor that the member 12 can be adjusted upwardly until it rests firmly upon the ball-bearings D, the flange 14c beingknurled or otherwise roughened to provide a finger grip, so that it may be readily rotated to adjust it inwardly or outwardly relative to the tubular member 2.

By reference to Fig. 2, it will be noted that the shank E, irrespective of the adjustment of the member 12, is'supported at its tubular member 2 and at its lower portion by the ball-bearings D and the adjustable member 12. hence said shank E, while free to rotate, is reliably held in vertical position and cannot assume an inclined position such as it commonly assumes when supported in the usual manner.

From the foregoing description it is apparent that T have produced a mounting for casters which. is well ada ted for the purpose intended. and while I have shownand described the preferred construction, combination. and arrangement of parts, I reserve the right to make such changes as properly fall within the spirit and scope of the claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

In combination with a piece of furniture equipped. with casters having verticallyex tending shanks and ball-bearings, a tubular provided With a seat to receive the upper 1 member adapted to seat in a counterbore in portion of the ball-bearing of the caster, the furniture and having a reduced upper substantially as described.
